Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.

Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).

A case of traumatic uterine avulsion in pregnancy.

Complete uterine avulsion is an extremely rare complication of trauma sustained during pregnancy. We present the case of a 21-year-old nullipara at 16 weeks' gestation who was involved in a high-speed motor vehicle collision with subsequent fetal demise. Initially she was hemodynamically stable and demonstrated small amounts of intraabdominal free fluid, therefore multidisciplinary conservative measures were undertaken.

Side-to-end reanastomosis after low-anterior resection (STELAR): Outcomes, feasibility, and description of procedure performed by a gynecologic oncology service.

Background And Objectives: Low anterior rectosigmoid resection for a gynecologic disease is usually performed in concert with other procedures and can result in significant morbidity should anastomotic complication occur. This study examined surgical outcomes of side-to-end reanastomosis after low anterior resection (STELAR) performed by gynecologic oncology service.

Methods: This is a case series examining consecutive patients who underwent STELAR for gynecologic indications by a single gynecologic oncology group from 2009 to 2018.

Proposal of a simple 2-hand technique at cesarean hysterectomy for placenta accreta spectrum.

Placenta accreta spectrum (PAS) encompasses a range of disorders of placental trophoblastic tissue that is morbidly adherent to the underlying gravid uterus. Women with PAS commonly undergo surgical treatment with hysterectomy at cesarean delivery that is associated with significant surgical morbidity and mortality. Increased vascularity due to gestational change and the abnormally enlarged lower uterine segment due to the location of placenta make the surgery complex and morbid.

Wait-time for hysterectomy and survival of women with early-stage cervical cancer: A clinical implication during the coronavirus pandemic.

Objective: A global pandemic caused by a novel coronavirus (Covid-19) has created unique challenges to providing timely care for cancer patients. In early-stage cervical cancer, postponing hysterectomy for 6-8 weeks is suggested as a possible option in the Covid-19 burdened hospitals. Yet, literature examining the impact of surgery wait-time on survival in early-stage cervical cancer remains scarce.

Simultaneous ammonium and phosphate recovery and stabilization from urban sewage sludge anaerobic digestates using reactive sorbents.

The use of low-cost inorganic sorbents as a new sustainable strategy to enhance the valorization of nutrients (N-P-K), from the urban water cycle (e.g., side streams from sewage sludge anaerobic digestion), in agriculture applications is presented.

Asymmetric electroosmotic pumping across porous media sandwiched with perforated ion-exchange membranes.

To have non-zero net flow in AC electroosmotic pumps, the electroosmosis (EO) has to be non-linear and asymmetric. This can be achieved due to ionic concentration polarization. This is known to occur close to micro-/nano-interfaces provided that the sizes of the nanopores are not too large compared to the Debye screening length.

Recovery of ammonia from domestic wastewater effluents as liquid fertilizers by integration of natural zeolites and hollow fibre membrane contactors.

The integration of up-concentration processes to increase the efficiency of primary sedimentation, as a solution to achieve energy neutral wastewater treatment plants, requires further post-treatment due to the missing ammonium removal stage. This study evaluated the use of zeolites as a post-treatment step, an alternative to the biological removal process. A natural granular clinoptilolite zeolite was evaluated as a sorbent media to remove low levels (up to 100mg-N/L) of ammonium from treated wastewater using batch and fixed bed columns.

Predictors of Hypomania During Ventral Capsule/Ventral Striatum Deep Brain Stimulation.

Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) is a novel therapy for neuropsychiatric disorders. Hypomania is a known complication of VC/VS DBS, but who is at risk is less understood. Factors such as family history, combined with details of DBS programming, might quantify that risk.

Rap1 maintains adhesion between cells to affect Egfr signaling and planar cell polarity in Drosophila.

The small GTPase Rap1 affects cell adhesion and cell motility in numerous developmental contexts. Loss of Rap1 in the Drosophila wing epithelium disrupts adherens junction localization, causing mutant cells to disperse, and dramatically alters epithelial cell shape. While the adhesive consequences of Rap1 inactivation have been well described in this system, the effects on cell signaling, cell fate specification, and tissue differentiation are not known.
